According to the report, Henderson was pulled over by campus police Sunday and found to have a blood-alcohol level of greater than 0.02, which is the legal limit for persons under the age of 21. Henderson, only a sophomore, is 20. He pleaded not guilty on Monday.

His suspension comes as a violation of the student-athlete code of conduct, the school announced, and Grizzles’ coach Wayne Tinkle says the plan of action is, “clear on the punishment, but it’s also important that Henderson learn and grow from the situation,” according to the AP.

Henderson has seen a significant increase in his minutes since his freshman season, now averaging 2.8 points and 2.2 rebounds in just over 12 minutes per game. His best game of the season came on Jan. 10 against North Dakota when he scored 12 points and grabbed five rebounds in a double-digit Montana win.
